  1. Presented by: Ying Hsu, Brian Eisemann, Frank Divita, E.H. Pechan & Associates, Inc. David Mobley & Lee Beck, EPA What’s New in SPECIATE 4.2?Emission Inventory ConferenceBaltimore MarylandApril 15, 2009

  2. What is SPECIATE? • Database of speciated emissions profiles by source category • Species include metals, ions, elements, organic and inorganic compounds • Consistent Units • Contains three categories: • Particulate matter (PM) • Volatile organic compounds (VOC) • Other Gases (e.g. Hg, NO/NO2/HONO, semi-volatile organic compounds) • PM profiles are size-segregated (e.g. PM10, PM2.5) • Housed in Microsoft Access database

  3. Development of SPECIATE • Collaboration involving: • EPA's Office of Research and Development (ORD) • Office of Air Quality Planning and Standards (OAQPS) • Office of Transportation and Air Quality (OTAQ) • Environment Canada • SPECIATE Workgroup

  4. Why Do We Need SPECIATE? • Create speciated emissions inventories for photochemical modeling • Estimate toxic air pollutant emissions from various emission sources • Provide input to source-receptor models (CMB) • Verify profiles derived from ambient measurements using multivariate receptor models (e.g., factor analysis and positive matrix factorization) • Provide a repository of compounds searchable by source category and pollutant

  5. Brief History of SPECIATE Database • Paper and computerized versions available in 1988 for EPA applications • First electronic version (CD) distributed to the user community in 1993 • SPECIATE 3.2 posted to EPA's CHIEF website in Nov 2002 • SPECIATE 4.0 posted to EPA's CHIEF website Jan 2007 • SPECIATE 4.1 completed October 2007 for Environment Canada; final results included in SPECIATE 4.2 • SPECIATE 4.2 – Final Report Expected in April 2009, Web Browser posted March 2009

  6. Brief History (continued) • SPECIATE 3.2 (2002) • Has a front-end via desk top application • 1503 PM profiles • 565 gas profiles • 890 unique species • SPECIATE 4.0 (2007) • Housed in MS Access® • 2,865 PM profiles • 1,215 gas profiles • 1,902 unique species

  7. SPECIATE 4.2 • 3,326 PM profiles; • 1,624 organic gas profiles; • 237 Other Gases profiles; • A total of 2,207 unique species • Composite profiles for 58 (47 PM and 11 VOC) source categories; • Every profile has been assigned to a SCC • An updated SCC-to-SPECIATE profile cross-reference table accounting for over 80% of national VOC and PM emissions in the 2002 National Emissions Inventory (NEI)

  8. SPECIATE 4.2 (continued) • Final Report is In-Press • VOC-to-TOG conversion factors for applicable gas profiles; • A protocol for expansion of the database; • A mapping of the new VOC compounds into model species categories; • Review and prioritization of 49 studies entailing 614 PM and 822 VOC profiles for potential inclusion in the future SPECIATE database. • Web application developed to provide access through a simple web interface - allows complex searches and downloads

  9. Example of SPECIATE Data

  10. Example Profiles • Motor Vehicle (1,653 profiles) • TOG; PM; SVOC; Hg; NO/NO2/HONO • Gasoline Exhaust • Gasoline Hot Soak • Liquid Gasoline • Diesel Exhaust • Tire Wear • Brake Wear • Diesel Headspace Evaporative • Gasoline Diurnal Evaporative

  11. Example Profiles (continued) • Agricultural Burning (78 profiles) • Rice Straw, Wheat Straw • VOC; PM

  12. Example Profiles (continued) • Forest Fire (99 profiles) VOC, PM • Ponderosa Pine • Loblolly Pine • Western Hemlock • Aceraceae/ Fagaceae • Palmae/ Pinaceae • Poaceae/Pinaceae • Fireplace/Wood Stove (144 profiles) VOC; PM • Pine • Oak • Eucalyptus

  13. SPECIATEDataDiagram

  14. The SPECIATE Data Browser • Web-based application • ColdFusion® and Oracle® • Accessed through internet browser • Allows data searches by pollutant, key word, and category • Allows data download • No need to purchase or use Access http://projects.pechan.com/ttn/speciate4.2/

  22. Conclusion • SPECIATE 4.2 and its Data browser represent a significant enhancement of the data available to characterize emissions by species and source category. • The SPECIATE Data Browser makes it easy for non Access users to view and use SPECIATE data • New source profiles and application features will be added In future revisions • You can help by supplying data • Electronic data preferred • Questions/Comments/Suggestions • Frank Divita - frank.divita@pechan.com • Lee Beck - beck.lee@epa.gov • http://cfpub.epa.gov/si/speciate/ • http://projects.pechan.com/ttn/speciate4.2/
